Abstract: The present disclosure provides a method and system for determining a pure electric available power and a vehicle, the method being applied to a vehicle including a fuel cell, the vehicle further including a battery pack and a motor, the fuel cell and the battery pack being electrically connected to the motor, wherein the method includes: monitoring a current travelling state of the vehicle and a current on-off state of the fuel cell; acquiring a maximum peak power outputted by the motor, a maximum output power of the battery pack and a starting-up power of the fuel cell; and according to the current travelling state, the current on-off state of the fuel cell, the maximum peak power, the maximum output power and the starting-up power, determining the pure electric available power. The present disclosure may quickly determine the pure electric available power, without complicated logical operation, and the operation states of the vehicle, the fuel cell system, the motor and the battery pack are taken into consideration at a same time, whereby the determined pure electric available power is closer to the actual available power.
